Title: Improvements relating to filters and purifiers employed for conditioning air, for example for respiration, by freeing it from poisonous gases and other injurious or undesired constituents
IPC: A62B18/08
Filed: 1935-09-09
Abstract: 445,457. Respiratory appliances. SOC. ITALIANA PIRELLI, 21, Via Fabio Filzi, Milan, Italy. Sept. 9, 1935, No. 25057. Convention date, Sept. 21, 1934. [Class 81 (ii)] In air or gas purifying apparatus, particularly individual and collective filters employed in removing noxious constituents from respired gases, the exhaust of moisture absorbing materials employed is indicated by causing the gases during passage through or after emergence from the materials, to traverse one or more elements which, in the presence of moisture, close the circuit of an electric signalling device or generate current for such a circuit. As shown applied to a respiratory filter containing a moisture absorbing mass 4, and an active filter mass 2 such as a catalytic carbon monoxide filter, an oxygen-generating peroxide, alkali hydroxide, or silica gel, a pair of metal plates 6 enclosing between them dry hygroscopic material 7 such as potassium hydroxide or calcium chloride, are embedded in the upper part of the mass 4 and are connected, by wires 11 passing through an insulated plug 8, to a battery 12, and to a lamp 14 and ammeter 15 either of which may be placed in circuit by a switch 13. The material 7 acts as an insulator when dry but completes the circuit when moistened. The plates 6 may be perforated. In an alternative construction the plates 6 are replaced by pairs of plates of different metals such as copper and zinc set parallel to the gas-path, the plates having dry hygroscopic material between them and being connected in series to form a battery energizing an external signal circuit when the material is moistened. Glass wool or like insulating material is packed between the pairs of plates. The filter container has an outlet 3 and an inlet closed by a plug 10. The signal device may comprise a glass phial containing a substance changing its colour on passage of current such as an aqueous solution of methyl orange containing an ionizable salt such as sodium chloride, or of decomposing so as to break the phial, such as acidulated water. The hygroscopic material between the signal plates may constitute the sole moisture-absorbing element of the filter.

Title: Coating glass
IPC: B05D1/26
Filed: 1975-06-11
Abstract: 1507996 Coating glass PILKINGTON BROS Ltd 9 June 1976 [11 June 1975] 25077/75 Heading C1M [Also in Division C7] A moving glass ribbon 21 is coated by directing gas onto a surface to be coated from a distributer extending transversely across the ribbon, so that the gas flows parallel to the glass under laminar flow conditions and uniformly across the width of the surface. The glass is preferably still hot from a forming process (e.g. a float, vertical-drawing or rolling process). The distributer (shown in crosssection) comprises a U-shaped channel 27 defined by shaped carbon blocks 50, 51, 52, 53 (and by the glass 21 itself), the gas being supplied to channel 27 from supply duct 41 via restrictor means 43 (to ensure uniform gas distribution across the ribbon width). Exhaust means (not shown) are provided for removal of excess coating gas. The temperature of the gas is preferably regulated to prevent deposition of solid material before the gas contacts the glass. Thus if the gas comprises a silane, the gas supply duct 41 may be cooled by water passing through ducts 39, 40. Alternatively, e.g. where metal vapour is used, heated oil may be passed through said ducts 39, 40. The gas may alternatively include metal carbonyl or acetylacetonate compounds. The gas preferably flows co-current with the glass ribbon at a Reynolds number below 2500.

Abstract: 297,574. Page, F. H., and Page, Ltd., H. Sept. 23, 1927. Bomb-dropping.-Relates to bomb-dropping and like devices comprising hooks released by a piston driven by the explosion of a cartridge in a cylinder, as described in Specifications 17346/15 and 255,240, and consists in mounting the cylinder in such a manner that it can be detached for cleaning. In the form shown in Figs. 1, 3 and 4, the cylinder A is mounted on a pivot pin B between the two plates C, C<1> of the frame of the apparatus, and the pivot pin B can slide cut from the closed position, Fig. 3, to the open position, Fig. 4, to allow the cylinder to be detached from the frame and pulled away from the piston D. The pivot pin B is made integral with a parallel pin B<4> formed with a head B<6> to prevent the complete withdrawal of the pin from the plate C<1>, and with a nick B<3> for engagement by a spring B<1> in the closed position. The piston D has a longitudinal slot to accommodate the pivot pin B, and is pivoted at the outer end to the lever E<1> which locks and releases the hook F<1>. In modifications, the cylinder is detachably screwed into a socket which is trunnioned on the frame or is fixed thereto, in which latter case the piston is not pivoted to the release lever but merely bears against it.

Filed: 1937-09-21
Abstract: 574,165. Aerial warfare. MARTIN, J. Sept. 21, 1937, No. 25574. [Class 9 (ii)] [Also in Group XXII] Aircraft are provided with means for severing cables or nets of a balloon barrage by cutters operated by an explosive. The leading edges 2, Fig. 1, of the wings of an aeroplane or a guard frame 4 in advance of the wings are fitted with brackets 26, Fig. 2, each carrying a shearing unit comprising a head 19 provided with anvils 21, and plungers 16 having cutting edges 17, the plungers being operated by the firing of an explosive charge, e.g. a cartridge 10. The cartridges 10 are held in the barrels 6 by screwed breech blocks 7 fitted with spring-urged firing pins 11 which are held cocked by sears 30 pivoted on a pin 31 in the bracket 26. The shearing unit may be pivoted, on the bracket 26 at 24 and retained in normal position by spring-plungers 27. When a severable obstruction such as a cable 20 is encountered by the aeroplane it is guided by the formation of the leading edge of the wing or of the guard frame into one of the jaws of a shearing unit, whereupon the unit is tilted about the pivot 24 to release the head 32 of the firing pin requiring to be operated, from the corresponding sear 30. The cable 20 is then severed by the blow of the cutting plunger resulting from the firing of the cartridge 10. The cutting plunger may have projections engaging guide slots in the barrel 6 so that after a certain movement of the plunger the slots are uncovered to allow the products of combustion to escape. According to a modification the shearing unit is stationary, the firing pins being held cocked by levers having arms extending across the jaws 23, so that when a cable enters the jaw, the corresponding 'lever is operated thereby releasing the firing pin to fire the cartridge. A plate 35 of curved form may be fitted to guide the cable into a cutting jaw. The movement of the obstruction into cutting position may be used to cause the explosive charge to be fired electrically.
